The RAND Conference on Fiscal Federalism and this collection of essays would not have been possible without the financial support provided by The James B. Irvine Foundation, the Weingart Foundation, and RAND. We are extremely grateful for this support. We also would like to offer special thanks to Edmund Edelman, former Los Angeles County Supervisor and now RAND Senior Fellow, who helped conceive of the conference and was instrumental in gaining the involvement of the many state, county, and local officials attending the conference.

As editors, we have been enormously impressed by the hard work and enthusiasm shown by our author-colleagues in preparing their papers, presenting their material during the conference, and making the final revisions. Their diligence and commitment have added immensely to the quality of this endeavor, and all readers are inevitably in their debt. We also wish to convey sincere appreciation to our reviewers, Kevin McCarthy, Albert Williams, Barbara Williams, and Charles Zwick, for their thorough, insightful comments and willingness to complete their reviews under the tight timeline required by the conference and the publication date. RAND's Publications group deserves a loud round of applause for their help in all phases of manuscript preparation and publishing, and we especially thank Peg Schumacher, Jane Ryan, Jeanne Heller, Janet DeLand, Betty Amo, Miriam Polon, and Janis Lane. Barry Balmat worked closely with us in structuring the conference and selecting the invitees, and his organizational skills were key to making the conference a success. Rebecca Sprigg, also a pleasure to work with, assisted Barry and did a superb job. Toby O'Brien and Nora Wolverton ably served as conference support staff. We thank you all.
